First impression with Ubuntu 7.10
Yesterday, I installed Ubuntu 7.10. This time, I downloaded the desktop image instead of the server version, which I learned from my previous experience. I was a little disappointed that 7.10 didn’t resolve the kernel/acpi issue that I had on a machine that I use. It’s not a big deal, I’ll just need to continue […]Read more "First impression with Ubuntu 7.10"
First impression on package mangement on Mac OS X
Ok. I’ve only used a Mac for a couple days, they were certainly long days with many steep learning experiences. Here are some of my comments: On Mac OS X, you have several options to install an application.

Build script for R / HDF5 on Solaris 10 x64 32bit
Rather than following my long howto, I’ve written a script to automate much of the work. You still need to follow the manual hand edits stated in step 5 of the howto. For debug build, follow the instructions stated in this howto. Below are the environment variable file and build script file that I used […]Read more "Build script for R / HDF5 on Solaris 10 x64 32bit"
Notes on creating a debug build of R/HDF5
In general, the goal of creating a debug build is to enable debug flag (-g) and remove all optimization flags such as: -O, -O2, -O3, -s, -fomit-frame-pointer, -fstack-check, etc. If you ever run into situations where you need to build a debug build of R/HDF5, here are my notes for Solaris. For Linux or other […]Read more "Notes on creating a debug build of R/HDF5"
UTF support in R
When I tried to compile R on Solaris 10 today, I noticed that R complained that it doesn’t support UTF locales. A check in the documentation showed that UTF-8 should be supported. A closer reading revealed that the example UTF encoding key is in lower case without dash “-“. i.e. “en_GB.utf8“. The default encoding key […]Read more "UTF support in R"

Notes on running NCSA HDFView
The HDFView “is a visual tool for browsing and editing NCSA HDF4 and HDF5 files.” The Linux version appears to be 32-bit and not having all the necessary 32-bit libraries caused my system unable to run it. So, I tried to run Solaris version. I had to tweak HDFVIEW_HOME and JAVAPATH variables in <HDFVIEW_HOME>/bin/hdfview.sh to […]Read more "Notes on running NCSA HDFView"
